Answer:
The value of test statistic
|Z| = |-2.2883| = 2.2883
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given that the mean of the Population = 57.7miles/gallon
The standard deviation of the Population = 1.9
The mean of sample x⁻ = 57.4
Given that the sample size 'n' =210
level of significance = 0.1
<u><em>Step(ii):-</em></u>
Test statistic


Z = -2.2883
|Z| = |-2.2883| = 2.2883
<u><em>Final answer:-</em></u>
The value of test statistic
|Z| = 2.2883
Answer:
64in
Step-by-step explanation:
for a four sided figure, you do base x height. volume isn't squared in Math.
F(x) = <span>3x/(8+x) = y
f^(-1) is the inverse function. As its name suggests if f(x) = y that we need to find a g(x) such that g(y) = x
In order to find f^(-1) switch x with y and solve for y
3y/(8+y) = x
x(8+y) = 3y
8x+xy = 3y
8x=3y-xy
8x = y(3-x)
y = 8x/(3-x)
f^(-1) = y = </span>8x/(3-x)
